A qualitative HCG blood test checks if there is a hormone called human chorionic gonadotropin in your blood. HCG is a hormone produced in the body during pregnancy.

How the Test is Performed
A blood sample is needed. This is most often taken from a vein. The procedure is called a venipuncture .
Venipuncture
Venipuncture is the collection of blood from a vein. It is most often done for laboratory testing.
How to Prepare for the Test
No special preparation is needed.
How the Test will Feel
When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing.
Why the Test is Performed
Most often, this test is performed to determine if you are pregnant. HCG level in the blood may also be high in women with certain types of ovarian tumors or in men with testicular tumors.
Normal Results
The test result will be reported as negative or positive.
- The test is negative if you are not pregnant.
- The test is positive if you are pregnant.
What Abnormal Results Mean
If your blood HCG is positive and you DO NOT have a pregnancy properly implanted in the uterus, it may indicate:
-
Ectopic pregnancy
Ectopic pregnancy
An ectopic pregnancy is a pregnancy that occurs outside the womb (uterus). It is life-threatening to the mother.
- Miscarriage
-
Testicular cancer
(in men)
Testicular cancer
Testicular cancer is cancer that starts in the testicles. The testicles are the male reproductive glands located in the scrotum.
- Trophoblastic tumor
- Hydatidiform mole
-
Ovarian cancer
Ovarian cancer
Ovarian cancer is cancer that starts in the ovaries. The ovaries are the female reproductive organs that produce eggs.
Risks
Risks of having blood drawn are slight, but may include:
- Excessive bleeding
- Fainting or feeling lightheaded
- Blood accumulating under the skin (hematoma)
- Infection (a slight risk any time the skin is broken)
Considerations
False positive tests may occur when certain hormones are increased, such as after menopause or when taking hormone supplements.
Menopause
Menopause is the time in a woman's life when her periods (menstruation) stop. Most often, it is a natural, normal body change that most often occurs...
A pregnancy test is considered to be very accurate. When the test is negative but pregnancy is still suspected, the test should be repeated in 1 week.

Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
